Coal Slurry Pumps
Coal slurry handling — from washery water to coal-ash slurry — involves fibrous, fine and sometimes stringy solids. HET non-clog and heavy slurry submersible pumps are engineered to keep coal slurry moving without blockage.
The Coal Challenge
Coal slurries can contain fibrous material, fine coal particles and abrasive ash. Clogging and choking are common with conventional pumps, along with wear from abrasive ash content.
What You Are Pumping
Coal slurry ranges from fine coal-water mixture to ash slurry with abrasive solids. It may contain fibrous or stringy matter that risks clogging, and variable solids concentration through the duty cycle.
Why It Is Difficult
The main challenge is preventing clogging from fibrous and fibrous-fine solids while handling abrasive ash. Reliable solids handling and non-clog impeller design are essential for continuous coal-slurry duty.
The HET Solution for This Application
NSEW — Slurry / Non-Clog Submersible Pump
Why HET for This Duty
HET non-clog slurry submersible pumps are engineered for fibrous and semi-solid slurry where clogging is the primary risk. Application-based selection and performance testing support reliable coal-slurry handling.
Selection Considerations
Confirm flow, head, solids type and fibrous content. For highly abrasive coal-ash slurry, the SSEW heavy slurry family may be more suitable — request engineering review for your specific duty.
